According to the statistics compiled by the Central Epidemic Command Center (CECC) for Dengue Outbreak, a total of additional 85 indigenous dengue cases were confirmed in Taiwan on December 18, 2015, including 78 cases in Kaohsiung City, 2 cases in Tainan City and 5 cases in Pingtung City.

Since this summer, a cumulative total of 42,353 indigenous dengue cases, including 22,732 cases in Tainan City, 18,733 cases in Kaohsiung City and 367 cases in Pingtung City.

In addition, the CECC announced plans for reduced use of  chemical vector control to minimize impact on the environment.

This decision is based on information during the past 25 years in which the overall dengue incidence has continued to drastically increase in Southeast Asia despite implementation of World Health Organization (WHO) guidelines as chemical control being the primary strategy for dengue prevention and control.

CECC says it will focus more on community-based source reduction and implement chemical control as the supplementary measure from now on.
